I know this video is 3 yrs. old but I just had to comment on it, in case anyone sees this. My senior cat started drinking with her paw like this and I couldn't figure out why as she had always lapped her water the usual way; but I got to thinking maybe she had a bad tooth (or more than one)...I had always served her water cold, and cold liquid hurts if you have tooth issues; so I started giving her warm water in her bowl and she immediately went back to lapping. So any time a cat starts doing this their humans should have their teeth checked. Try giving warm water and if they lap it, then you know.
